other similar material, I prefer to use the In that torm of the resilient fingers illustrated in Figs. 5 and 6, the fingers 22 may be arranged between alternate pairs of prongs so as to provide a set of four fingers instead of the set of eight shown in Figs. 1 to l inclusive. The resilient fingers 22 are further illustrated as modified to the extent that the ends 28 are bent downwardly and out wardly so as to provide a closed, substantially cylindrical surface 24 for engaging the stud.

The remaining projections 25 while integral with the wall 12 and arranged between the other alternate pairs of prongs, are of insufficient length to act as stud engaging members, but serve not only to brace the socket but also may serve to engage the surface to which the socket is attached and thereby serve as stops to prevent the fastener from cutting its way through the carpet, the fingers 15,20 and 22 also serving to prevent such cutting. 7

It will be understood that in all the various possible shapes of the resilient fingers, said fingers are integral with the wall 12 and bent inwardly and downwardly or laterally therefrom, and are of sufficient length to allow the substantially free inner ends thereof to inwardly overhang the edge of the aperture 11 for the purpose of engaging the stud passed through said aperture.

It will also be understood that the ends 0 the resilient fingers are suitably curved to resist the withdrawal of the stud from the socket after it once has been inserted thereinto, since the ends of said fingers are designed to engage the constricted portion of any of the well known types of studswhich are customarily used in connection with shallow sockets, and'hence which need not be shown. It will be further understood that the various fingers 15, 20 and 22 are designed to yield on the advance of the stud through the aperture 11 under the action of the stud on the free ends of the fingers, so as to allow the passage of said stud through the aperture and past the ends of the resilient fingers without the necessity of applying undue pressure to the'stud.

Said resilient fingers also yield in substantially the same manner when the stud is forcibly withdrawn from the socket.

It will be seen that I have provided a simple socket adapted to be readily attached to another article and made of one piece of material, wherein resilient fingers for engaging and temporarily retaining a stud are provided, and wherein said fingers are protected from injury by a bottom wall.

' It will also be understood that-'whileI have shown and described various forms of my invention as illustrative thereof, I do not intend to limit myself thereto, but intend to 1 claim:

1. A pronged socket comprising an outer wall, spaced prongs integral with and outstanding from the upper end of said wall,

a bottom wall portion having an aperture the outer wall and bent inwardly therefrom and extending from said upper end to a point inwardly of the edge of the aperture for engaging said stud.

2. A stud-engaging fastener element of a single piece of material, including an outer wall and an apertured bottom wall, spaced prongs outstanding from and integral with the upper end of said outer wall, and yieldable fingers integral withsaid outer wall and bent from the upper end thereof, the inner ends of said fingers being free and curved, and projecting slightly inwardly of the aperture of said bottom wall and being adapted to engage the constricted portion of a cooperating stud passed through said aperture 3. In a socket fastener element, a bottom wall having an aperture therein, a substantially cylindrical outer wall, a pair of prongs continuous with said outer wall and spaced apart and extending beyond a peripheral end of said outer wall, and a finger integral with said outer wall and bent radially inwardly from the same peripheral end between said prongs 'to overhang the aperture of said bottom wall and to engage a stud passed through the aperture.

In a stu-d engagi-ng socket fastener, an apertured bottom wall adapted to have a stud element passed therethroug-h, spaced prongs integral. with and outstanding substantially perpendicularly to means formed on the outer periphery of said wall, and resilient members bent radially inwardly of said apertured wall and from said means on the outer periphery, and arranged between said prongs with their free ends curved and terminating adjacent the edge of said aperture for engagin a constricted portion of a stud passed t rough the aperture.

5. In a stud-engaging ment, a flat circular apertured bottom wall, a substantially cylindrical wall integral with and substantially perpendicular to said bottom wall, spaced members on the upper end of the cylindrical wall for attaching said element to an article, and yieldable elements bent inwardly from and integral with said end of said cylindrical-wall and projecting inwardly past the edge of the aperture in said bottom wall for engaging the headof a stud passed through said aperture.
